What happens if a chemical equation is not balanced?

Answer. If a chemical equation is not balanced it implies that either mass has been created or destroyed which is a contradiction to law of conversation of mass which states that matter can niether be created nor destroyed .

Is co2 acidic or basic?

Carbon dioxide, which is mildly acidic, is a waste product of the processing (metabolism) of oxygen and nutrients (which all cells need) and, as such, is constantly produced by cells. It then passes from the cells into the blood. The blood carries carbon dioxide to the lungs, where it is exhaled.

What happens if pH is too high in pool?

If the pH gets higher than 7.8, the water is becoming too alkaline. When water is too alkaline, it reduces the effectiveness of the chlorine — the pool chemical that kills pathogens. Water with a pH that’s too high also can cause skin rashes, cloudy water and scaling on pool equipment.

How many bonds can chlorine form?

Each chlorine atom contributes one electron to the bonded pair shared by the two atoms. The remaining six valence electrons of each chlorine atom are not involved in bonding….Covalent Bonds.

Atom Valence
Bromine 1
Chlorine 1
Iodine 1
Oxygen 2

What is an unbalanced equation?

If the number of atoms of each element in reactants is not equal to the number of atoms of each element present in product, then the chemical equation is called unbalanced chemical equation.

What are two reasons for balancing chemical equations?

Chemical equations are balanced in order to: 1) satisfy the Law of Conservation of Mass, and 2) establish the mole relationships needed for stoichiometric calculations. The Law of Conservation of Mass: The Law of Conservation of Mass states that mass cannot be created or destroyed.

How is hydrogen chlorine and HCl balanced?

1) H2 (g ) + Cl2(g) => 2 HCL (l) . chemical equation is balanced because to follow the law of conservation of that is. in a balanced chemical equation has equal number of atoms of different elements in the reactant as well as product.

Why chlorine is written as CL2?

Answer. Answer: Explanation: We write chlorine as CL2 because chlorine is a non metallic gas . Also as chlorine is a gas it occurs in diatomic form as cl2 such as hydrogen(h2).

What is the chemical equation for HCl?

Hydrogen chloride may be formed by the direct combination of chlorine (Cl2) gas and hydrogen (H2) gas; the reaction is rapid at temperatures above 250 °C (482 °F). The reaction, represented by the equation H2 + Cl2 → 2HCl, is accompanied by evolution of heat and appears to be accelerated by moisture.

Is chlorine Cl or CI?

Chlorine is a chemical element with symbol Cl and atomic number 17. Classified as a halogen, Chlorine is a gas at room temperature….Chlorine.


Does increasing chlorine lower pH?

High chlorine levels decrease the pH of your pool’s water, making it more acidic. The more acidic the water, the higher the likelihood of corrosion. This corrosion can affect metal piping, equipment, and the surface of your pool (tiles, liners, concrete, etc.).

How do I make my pool water crystal clear?

How to Make Your Pool Crystal Clear Again

  1. Keep Up with pH and Chlorine Levels. Do you have a water testing device in your supply kit?
  2. Run That Filter. It’s recommended that you run your filter for 8 to 10 hours a day when using your pool.
  3. Skim, Skim, Skim. Yes, something that simple can be the trick to clear water.
  4. Shock the Pool Once a Week.

What is the pH of chlorine?


What is the goal of balancing a chemical equation?

A balanced equation obeys the Law of Conservation of Mass. This is an important guiding principal in science. Finally, a balanced equation lets up predict the amount of reactants needed and the amount of products formed.

Is a chemical equation balanced?

If each side of the equation has the same number of atoms of a given element, that element is balanced. If all elements are balanced, the equation is balanced.

Do you reduce when balancing chemical equations?

When balancing chemical equations, the last step is to add coefficients to oxygen and hydrogen atoms. However, chemists always write the simplest equation, so check your work to make sure you can’t reduce your coefficients. This is how you balance a simple chemical equation for mass.

How do you balance chemical equations?

In order to balance the chemical equation, you need to make sure the number of atoms of each element on the reactant side is equal to the number of atoms of each element on the product side. In order make both sides equal, you will need to multiply the number of atoms in each element until both sides are equal.
